Rotary Switches: Application Field and Working Principle

Rotary switches are used in a variety of applications, including electrical components, automated controls and communication systems. They are available in a range of sizes and configurations that make them suitable for a variety of tasks. One of the most popular types of rotary switches is the 71BS30-10-1-03S. This switch is commonly used in telecom and audio products, as well as in some industrial and automotive applications.A rotary switch consists of a switch mechanism, or rotor, that connects two or more electrical contacts, allowing for the connection of various devices. The switch is actuated by rotating the rotor, which turns the contact points at a constant rate. The rotor is connected to an outer casing that is usually made of a hard plastic or metal material. This housing typically contains several connection ports, which can be used to wire the switch to the devices it will be connecting.The 71BS30-10-1-03S is a three-position single-pole rotary switch. It is a double-throw switch, meaning that it can be connected to two separate electrical circuits. The switch can be operated in either a series or parallel fashion, allowing for several combinations of contacts. When the switch is rotated in one direction, it will connect the first set of contacts, and when rotated in the opposite direction, it will break the connection and connect the second set of contacts.The switch is typically used in applications where it needs to be operated from a distance, such as remote control systems or production line automation. It can also be used to control current flow or to select different operating modes. The switch is available in various versions, including panel-mounted versions for easy mounting and a version with a dust proof cover that prevents dust and dirt from entering the mechanism.The 71BS30-10-1-03S is also used in situations that require a higher load capacity. It has a rating of up to 10 amps and a voltage rating of 250 volts. This makes it suitable for medium-size applications, such as commercial refrigeration, lighting and small motor control. It is also popular in computers and communication systems because of its accuracy, reliability and durability.The working principle of a rotary switch is fairly simple. When the rotor is turned, it transfers its rotational energy into mechanical energy, which is used to move the contact points. When the contact points meet, an electrical connection is established between the two points. The electrical connection remains until the rotor is turned in the opposite direction, which breaks the connection and moves the contact points apart.The 71BS30-10-1-03S is a versatile switch that provides reliable connections in a variety of applications. Its high load capacity, accuracy and durability make it suitable for a wide range of applications. With its easy installation, long-term reliability and multiple connection options, it is an excellent choice for many different types of applications.
